803-F412TRH

The Allen-Bradley 803-F412TRH is a heavy-duty rotating cam limit switch with a long life expectancy that comes with 4 circuits, Type 1 and Type 13 enclosure ratings, a right-hand standard shaft extension, and whose cams are internally adjustable. Its external dwell time and timing settings can also be adjusted via a screwdriver even while the device is in motion and it is fully capable of rotation in a clockwise or counterclockwise direction when mounted on any type of plane. Allen-Bradley 803 series switches, such as the 803-F412TRH, come with a spring-loaded cam-roller assembly which is mounted to the contact base. This switch is also a Style F switch which has a cam duration that ranges from a minimum duration of 12Ëš to a maximum duration of 348°, 10 Amp. snap action N. O. (normally open) and N. C. (normally closed) contacts, and a maximum shaft speed of 150 RPM.

Measuring approximately 7.06 x 4.81 x 2.41 inches and weighing around 12 lbs, the 803-F412TRH switch is ideal for use with machines featuring repetitive operation cycles where the shaft rotation and the machine motion are correlated to each other. It is also used for applications such as steel forming, waterway gate operations, assembly machines, and punch presses. Its operating temperature is from -30-66 °C, while its storage temperature is from -30-93 °C. The 803-F412TRH’s typical shaft torques are 0.5 pounds on an inch with the cam roller in the valley, 3 pounds on an inch when the cam roller rides on the lobe, and 7 pounds on an inch when the cam roller rides up the cam ramp.
